The in-situ observation of microstructural evolution under electron irradiation was performed in order to experimentally estimate the mobility vacancy and interstitial 316 stainless steel CoCrFeNi-base high entropy alloys. migration energy CoCrFeNiMn CoCrFeNiAl0.3 estimated be lower higher compared with that steel, respectively. While, those alloys seems almost same. increase is probably due a ...

With the complexity of structure aero-engine turbine blades, blade wall thickness continues to decrease. It is found that when decreases a certain extent, its mechanical properties will decline significantly. extremely important study this phenomenon significant in caused by thickness. In paper, creep behavior second-generation Ni3Al-based single crystal superalloy with different thicknesses an...

Composite surface structures inspired by the functional of Scapharca subcrenata shells can improve tribological properties effectively, composed ordered “U”- shape micro-grooves and solid lubricant Sn-3.0Ag-0.5Cu (SAC305) alloys. A series wear tests were conducted to further investigate formation characteristics self-compensating lubrication film, then mathematical model spreading tribofilm cou...
